mikejuk writes: Two former Facebook developers have created a new database that they say is the world’s fastest and it is MySQL compatible.According to former Facebook developers Eric Frenkiel and Nikita Shamgunov, MemSQL, the database they have developed over the past year, is thirty times faster than conventional disk-based databases. MemSQL has put together a video showing MySQL versus MemSQL carrying out a sequence of queries, in which MySQL performs at around 3,500 queries per second, while MemSQL achieves around 80,000 queries per second.The documentation says that MemSQL writes back to disk/SSD as soon as the transaction is acknowledged in memory, and that using a combination of write-ahead logging and snapshotting ensures your data is secure.There is a free version but so far how much a full version will cost isn't given.
